Definitions

  • the present invention relates to a mixture that increases the resistance of polymeric materials, particularly of polycarbonate materials against scratching and against the effects of alkaline substances, and to a method for preparing and applying said mixture.
  • the polymeric material with such advantageous features as lightness, practical usage and low cost, are used instead of the glass based material, in the domestic appliances, for instance in washing machines, the physical strength of such material is not sufficient and they are scratched and influenced by the alkaline material.
  • the coating technologies are employed in order to produce material with more superior properties and with higher additional values by coating all kinds of surfaces with a material that will give different thickness and properties to said surfaces.
  • the sol-gel technology is one of the leading technologies, being preferred due to its various advantages and the superior physical, mechanical and chemical properties it provides to the material to be coated, as well as the extension of the service usage life of said material.
  • the sol-gel technique consists of applying the combination of organic polymeric materials and oxidized or not oxidized inorganic ceramic materials and/or a composite mixture formed of organic modified non- metallic compounds, to the surface. These techniques are designed by using different properties of the organic and inorganic material, according to the intended function of the desired coating and are applied in the suitable process with suitable combinations.
  • reaction is carried out in water or in an organic solvent.
  • a colloidal solution (SOL) comprising particles with nanometric (nm) dimensions, passes to a two-phased gel (GEL) (position) state as the result of the reaction and process while forming the inorg-tnic polymeric net structure of the hydrolyzable compounds, such as metal (position) state as the result of the reaction and process while forming the inorganic polymeric net structure of the hydrolyzable compounds, such as metal alkoxides, as the result of hydrolyzation-condensation reactions, the organic polymeric net layer is formed in the system by the addition of organic compounds.
  • the organic groups have two important functions:
  • the organic groups modify the inorganic net by carrying their properties to the inorganic net.
  • They form an organic polymeric net by being added in a polymerized form to the inorganic net.
  • the sol-gel technique is the technique for forming the organic polymeric net structure of the organic modified alkoxid compounds by using the hydrolyzation and condensation reactions.
  • the object of the present invention is to realize a mixture to be used for the coating of polymeric materials, particularly of polycarbonate materials in order to increase their resistance against scratching and against the effects of alkaline substances, and, a method for preparing and applying said mixture.
  • the mixture according to the invention comprises an epoxysilane compound to provide the inorganic polymerisation, an epoxy compound to provide the organic modification, a F-silan to provide the coated surface with hydrophobic properties and a metal alkoxide to harden the coating, which in turn provides resistance against alkali.
  • epoxy-containing silanes that provide the inorganic polymerization are listed below:
  • Aiternative 1 G YEO ⁇ -Gly ⁇ dox propyltrieth ⁇ xysilan
  • the mixture is composed of GLYEO (3- Glycidoxypropyltriethoxysilan), as the epoxy-silane that provides the inorganic polymerization, Araldite GZ 601 as an epoxy compound for organic modification, Tridecafluoro-l,l,2,2-tetrahydro-octyl-l-triethoxysilan
  • the surface of the substrate is cleaned to eliminate grease and dirt, surface activity is enhanced, for instance by the corona method, in order to increase the binding and adhering properties between the surface and the coating, and the surface is cleaned again.
  • the mixture is applied onto the surface, the coated plates are dried at a temperature between 25-250°C for 5-120 minutes, after they are allowed to stay at the room temperature for 10-60 minutes.
  • the surface is coated by immersing the material to be coated into the mixture and drawing it out at a certain speed.
  • the surface is coated by spraying the mixture onto said surface.
